Instead of having gas power we would have our energy run on solar power, which is better for the environment than having gas powered appliances and nuclear energy.

I agree with this. I think that if we transitioned from coal and burning fossil fuels as our primary source of energy to more renewable sources of energy that this could really help the environment by lowering our carbon emissions.

Solar power is a good solution, though it's expensive from what I've heard. Wind power could work as a solution too.

Nuclear fusion could also work as a clean energy source... although we would need a good supply of helium 3 first.

These are all good options, but none of them are going to go through until someone develops a cheaper way to make them.

I agree. Not every company, home and building have the money for solar panels or other environmental friendly energy sources. Also, you have to consider location. For example here in Seattle we don't get a lot of sun during the winter and fall. Even when we do, its not enough to run a building solely on solar power. These energy sources are not reliable enough to implement every where, not to mention it is very expensive.

once we figure out how to make cheap eco friendly energy it will open more doors for us

I've heard a lot about the fact that we need to make solar energy more affordable for it to actually be accepted by mass amounts of people, which is a huge issue in order for families and bisnesusses to realistically be able to use it. But how are we actually going to be able to make it affordable? What needs to change?
